GOVNET In the Works

This network would be "separate from the Internet to keep it safe from hackers or terrorists" according to Richard Clarke, the head of the president's "cyberspace security adviser." Whatever happened to government not being above the people?" Clarke is the guy who's been crying "cyber Pearl Harbor" for a few years; apparently if you cry wolf long enough you get promoted. His request (.doc format) is informative. I should point out that the U.S. military already has such a network (I'm not even going to ask why the Feds can't piggy-back on it), so GOVNET would be for critically-important government agencies like the Department of Agriculture to communicate.
In the US Air Force, they refer to the internet as NIPRNET (Non-secure IP Router Network). Only unclassified info is sent across it, and sensitive unclassified or privacy act info is restricted to
The other network is called SIPRNET (Secret IP Router Network). On military installations its conduit is encased in concrete, junction boxes are alarmed, & cable drops are only in secure areas. Off the installations it's encrypted. I imagine the encryption is pretty strong since NSA designs the algorithms.
